Tina, a former hairdresser, was diagnosed with signet ring cell adenocarcinoma, a rare and difficult to treat form of stomach cancer that is almost immune to chemotherapy.

The cancer tends to affect the glandular cells lining the stomach.

It is hoped the immunotherapy will boost her bodies natural defences to fight the cancer.

Tina, pictured with her eldest son, believes immunotherapy is her last hope

Her close friend Laura Obradovic-Eaves said: "Immunotherapy is available here on the NHS but has only been approved for certain cancers and has not been approved for stomach cancer, despite evidence showing it has the potential to increase life expectancy dramatically in advanced gastric cancer compared to chemotherapy.

"The family have argued their case to the NHS and asked them to skip the formalities of approval and give her the treatment here but so far they are refusing to help Tina."
